设置docker本地镜像仓库

1、部署docker registry

1.1 拉取registry镜像#docker pull docker.io/registry Trying to pull repository docker.io/library/registry ... sha256:0e40793ad06ac099ba63b5a8fae7a83288e64b50fe2eafa2b59741de85fd3b97: Pulling from docker.io/library/registryb7f33cc0b48e: Pull complete 46730e1e05c9: Pull complete 458210699647: Pull complete 0cf045fea0fd: Pull complete b78a03aa98b7: Pull complete Digest: sha256:0e40793ad06ac099ba63b5a8fae7a83288e64b50fe2eafa2b59741de85fd3b97Status: Downloaded newer image for docker.io/registry:latest

1.2 启动registry

#docker run -d -p 5000:5000 --name=registry --restart=always --privileged=true --log-driver=none -v /data/registrydata:/tmp/registry registry其中，/data/registrydata是一个比较大的系统分区，今后镜像仓库中的全部数据都会保存在这个目录下。设置主机名字解析如果有内部dns则可以在dns上配置解析，如果没有则配置host文件

3、更改名称并推送

#docker tag docker.io/registry dockeregistry:5000/registry:latest

#docker tag registry.access.redhat.com/rhel7/pod-infrastructure:latest dockeregistry:5000/pod-infrastructure:latest#docker push dockeregistry:5000/registry:latest

docker push dockeregistry:5000/pod-infrastructure

在这里一般会报：Get : http: server gave HTTP response to HTTPS client的错误

解决办法：修改/etc/docker/daemon.json，在里面添加：{ "insecure-registries":["dockeregistry:5000"] }

重启docker

验证

4.1、修改客户端hosts文件，在里面添加仓库主机记录

4.2、修改docker配置文件

4.3、重启docker

4.4、从仓库拉取镜像

验证正确 ，配置完成
